A male who despite being caring and respectful to his female friends and acquaintances will never become anything more than "just a friend" to them. These guys will often pay attention and offer advice to their attractive female friends problems about their arrogant, douche-bag boyfriend only to see her dump that asshole and end up with someone even worse than him. This is because the majority of women, especially in their teenage years want to find muscular, good-looking, fashion conscious, pricks with enough confidence to diminish their insecurities enough so they can sleep at night without cutting themselves or consulting bulimia. Unfortunately this leaves the good guy in the shade, despite him being a better person, and being ten times the man her boyfriend is. Usually when girls say they want a "nice guy" he's usually some pantload with a foreign accent and a weird hairstyle. Luckily not all girls are like this and when the good guy finds these girls, he'll realize good things come to those who wait.
